If you have a frozen roast and need to cook it in the oven, there are a few things to keep in mind. First, you’ll want to allow the roast to thaw in the fridge for 24 hours before cooking. This will help ensure that it cooks evenly.
Once it’s thawed, remove the roast from the packaging and pat dry with paper towels. Preheat your oven to 350 degrees Fahrenheit and season the roast with salt, pepper, and any other desired herbs or spices. Place the roast on a rack in a roasting pan and cook for about 2 hours, or until it reaches an internal temperature of 145 degrees Fahrenheit.
Let the roast rest for at least 10 minutes before slicing and serving. Enjoy!
- Preheat oven to 375 degrees F (190 degrees C)
- Place roast in a roasting pan with fat side up
- Spread 1/2 cup of the beef broth over the top of the roast
- Bake uncovered for 1 hour and 15 minutes in the preheated oven, basting every 15 minutes with the pan juices
- Reduce oven temperature to 350 degrees F (175 degrees C), and spread another 1/2 cup beef broth over the roast
- Continue baking for an additional 45 minutes to 1 hour, or until internal temperature of roast is at least 145 degrees F (63 degrees C)
- 6 Remove from oven, and let rest for 10 to 15 minutes before carving into thin slices against the grain

Can You Cook a Frozen Roast Without Thawing?
There are a few different methods that you can use to cook a frozen roast without thawing it first. The most common method is to cook the roast in the oven at a lower temperature than you would if it were thawed. This will take longer, but if you’re careful not to overcook it, the results can be just as good.
Another option is to sear the frozen roast in a hot pan on the stovetop. This will help to seal in the juices and prevent the meat from drying out. Once it’s browned all over, you can transfer it to a slow cooker or an Instant Pot set on low heat and let it cook until tender.
Whatever method you choose, make sure to allow enough time for the roast to cook all the way through. A good rule of thumb is to add an extra 30 minutes to the cooking time for every pound of meat. So, if your roast is three pounds, plan on cooking it for at least 90 minutes total.
How Long Does It Take a Roast to Cook from Frozen?
Assuming you are cooking a frozen roast in the oven, it will take about 50% longer to cook than if it were thawed. So, if your recipe calls for a 3-hour roast, plan on cooking it for approximately 4.5 hours if it is frozen. Of course, this is just a general guideline and your best bet is to use a meat thermometer to ensure that your roast reaches the proper internal temperature (165 degrees F for poultry and 145 degrees F for beef, pork or lamb).

How Long Do You Cook a Frozen Roast in the Oven
Most people don’t realize that you can cook a frozen roast in the oven. It’s actually very simple to do and only requires a few extra minutes of cooking time. Here’s how long you need to cook a frozen roast in the oven:
For a 3-pound roast, cook it in the oven at 375 degrees Fahrenheit for about 2 hours. For a 4-pound roast, cook it for about 2 1/2 hours. And for a 5-pound roast, cook it for about 3 hours.
Keep in mind that these cooking times are just estimates. The best way to know when your roast is done is to use a meat thermometer. Stick it into the thickest part of the meat and wait until it reaches an internal temperature of 145 degrees Fahrenheit.
How to Cook a Frozen Roast
If you’re like me, you might not be the best at planning ahead. That’s why I’m here to show you how to cook a frozen roast! This is a great method for those days when you forget to take your meat out of the freezer, or if you just don’t have time to wait for it to thaw.
Here’s what you’ll need:
-A frozen roast (beef, pork, or lamb will work)
-Your favorite seasoning blend
-A little bit of oil
-A roasting pan or Dutch oven
-Some water or beef broth
First things first, preheat your oven to 325 degrees F. Then, take your frozen roast and rub it all over with some oil. This will help the seasoning stick and also help prevent the meat from drying out as it cooks. Next, season your roast generously with whatever spices and herbs you like.
I like to use a simple garlic and herb blend, but feel free to get creative!
Once your roast is seasoned, place it in a roasting pan or Dutch oven along with a cup or so of water or beef broth. This will keep the meat moist as it cooks and also help create some delicious gravy later on.
Cover the pan tightly with foil or a lid and place it in the preheated oven.
Serve with roasted vegetables and enjoy!
